| X-ray analysis deciphers master regulator important for skin cancer Posted: 01 Dec 2012 05:59 AM PST Scientists have uncovered the molecular structure of a master regulator central to the most deadly form of skin cancer, melanoma. The results throw new light on the workings of the so-called Microphthalmia-associated Transcription Factor MITF, that is not only connected to skin cancer, but also to a variety of hereditary diseases.  |
| Extended sleep reduces pain sensitivity Posted: 01 Dec 2012 05:59 AM PST A new study suggests that extending nightly sleep in mildly sleepy, healthy adults increases daytime alertness and reduces pain sensitivity.  |
| Lung cancer patients with pockets of resistance prolong disease control by 'weeding the garden' Posted: 01 Dec 2012 05:59 AM PST This study of 65 patients showed that continuing either crizotinib or erlotinib after the treatment of resistant pockets with focused radiation ("weeding the garden") was associated with more than half a year of additional cancer control.  |
| Steroid injection linked with significant bone loss in postmenopausal women treated for back pain Posted: 01 Dec 2012 05:59 AM PST Postmenopausal women suffered significant bone density loss in their hip after they were treated with an epidural steroid injection for back pain relief, according to a new study. Bone density loss after six months was six times greater when compared to the typical bone density loss seen in a year in a postmenopausal woman who doesn't receive steroid injection, researchers say.  |
| Native Americans and Northern Europeans more closely related than previously thought Posted: 30 Nov 2012 12:16 PM PST Using genetic analyses, scientists have discovered that Northern European populations descend from a mixture of two very different ancestral populations, and one of these populations is related to Native Americans.  |
| Young surgeons face special concerns with operating room distractions Posted: 29 Nov 2012 11:31 AM PST A study has found that young, less-experienced surgeons made major surgical mistakes almost half the time during a "simulated" gall bladder removal when they were distracted by noises, questions, conversation or other commotion in the operating room.  |
| Canada's first liver cell transplant: Performed on a three-month old girl Posted: 29 Nov 2012 10:06 AM PST Physicians successfully completed a series of liver cell transplants earlier this month on a three-month-old girl. It is the first time the procedure has been performed in Canada. The girl was born with a Urea Cycle Disorder, a rare genetic disease that causes ammonia to build up, which, if untreated, can lead to brain damage and death.  |
